It might help if you gave us some real information, like what hardware you're running, which actual version of CentOS and the kernel you are (and were) running, etc. Otherwise we're stabbing for a needle in a haystack.
I don't ever remember running a 'yum update' when I was using the 32-bit version and having it update me to a 64-bit kernel. I had to make that choice on my own first.
Hardware: Supermicro with Intel 64-bit CPU
The OS was CentOS 5.3 32-bit. I upgraded with the CentOS 5.5 x86_64 DVD, as stated earlier. I did not do the upgrade using yum, the upgrade broke yum.
You should not have done this. I guessing that the CentOS 5.5 installer is not bulleted proofed for this case (eg it assumed that you know what you were doing). In any case, this is not a supported way to go (documented or not). The 'updater' on the CentOS 5.5 x86_64 DVD is meant to go from CentOS < 5.5 x86_64 to CentOS 5.5 x86_64, NOT CentOS < 5.5 32-bit to CentOS 5.5 x86_64.
You should have made a backup and then did a fresh install.
The only good way to properly fix things is to backup your stuff (eg /home/ and stuff like /var/www/ (if you are running a web server)). Maybe backup selected files under /etc/ (eg passwd, shadow, group, etc.) and then do a fresh install (*reformat* /, /boot, /usr, etc.).
